One of two fired Broward sheriff’s deputies implicated in ex-lawyer Scott Rothstein’s criminal empire said he got into trouble by doing a favor for a boss.

Jeffrey Poole, in a sentencing memorandum to U.S. District Judge William P. Dimitrouleas, said he felt obliged to the sheriff’s head of internal affairs to fabricate the arrest of a lawyer’s ex-wife in 2009 at the behest of Rothstein.
